css platform connecting bridge area segmental manufacturing process and special oblique tire frame

Abstract

The invention provides a cross structure area segmentation manufacturing process of a CSS platform and a special-purpose inclined cutting jig frame. An inner side outer plate assembly is additionally arranged, an inner side outer plate inclined cutting jig frame is utilized in the assembly, therefore assembling and welding processes are improved, an assembling procedure and a welding position are optimized, fillet welds between a main structure of a cross structure area and an outer plate are all improved from elevation angle welding into horizontal fillet welding, welding quality and construction efficiency are improved, and special position full penetration welding requirements are met; by widening an operation range, a group technology of segmentation manufacturing processes is boosted, alternate operation choices of various work types are reduced, therefore the construction environment is improved, production efficiency is improved, and the segmentation manufacturing period is shortened.

Description

technical field [0001] The invention relates to a shipbuilding process, in particular to a segmental manufacturing process for a CSS platform connecting bridge area and a special oblique tire frame. Background technique [0002] The CSS platform is a two-body semi-submersible self-propelled auxiliary platform for living, which can meet the multiple purposes of human beings in the deep sea area. like figure 1 As shown, the connecting bridge area refers to the area connecting the double lower submerged bodies 300 and the upper hull 100 . In the CSS platform, this area has high requirements on the strength of the hull structure, and full UT non-destructive testing is required after the structure and the outer plate are welded, so the manufacturing difficulty is very high. [0003] see figure 2 , The traditional manufacturing process of the connecting bridge area is: set the horizontal tire frame counter-revolution with the deck as the reference plane, and bulk-pack the stru...

AI Technical Summary

Problems solved by technology

[0012] 1. The fillet welds between the strong structure in the connecting bridge area (such as vertical and horizontal wall plates 4, T profiles, etc.) image 3 , increasing the difficulty of welding and the workload of weld repair

[0013] 2. After the inner and outer panels are sealed, the internal space is narrow and the construction environment is poor

[0015] 4. It is not conducive to the advancement of group technology in the segmented production process
